/editvarpage?name=SOME_VARIABLE_NAME&redirectPage=RETURN_PAGE_NAME

That replaces the variable plugin that's in the user contribution library.

Indigo uses digest authentication when you have a username/password set in the Start Local Server dialog. In the curl examples above, you can specify your authentication like this:

curl -u user:password --digest [other options here]

That will allow your scripts to successfully authenticate and execute against a protected server.

To work around the Mac OS X “application isn't running” bug (error -600) that seems to be getting worse with each OS release, you can communicate between an external AppleScript (or app that runs AppleScripts) by using the curl command in a do shell script AppleScript call with the commands above to set (and get) information from the Indigo server.

For example, here's a simple AppleScript that will turn an Indigo device ON and then OFF:

set indigoServerIPandPort to "192.168.1.123:8176"
set indigoServerUsername to "username here"
set indigoServerPassword to "password here"
set devName to "office%20lamp" -- note spaces have to escaped by substituting with %20
set turnOffCommand to "curl -u " & indigoServerUsername & ":" & indigoServerPassword & " --digest -X PUT -d isOn=0 http://" & indigoServerIPandPort & "/devices/" & devName
set turnOnCommand to "curl -u " & indigoServerUsername & ":" & indigoServerPassword & " --digest -X PUT -d isOn=1 http://" & indigoServerIPandPort & "/devices/" & devName
do shell script turnOnCommand
do shell script turnOffCommand

And here's a simple AppleScript that will set the value of an Indigo variable:

set indigoServerIPandPort to "192.168.1.123:8176"
set indigoServerUsername to "username here"
set indigoServerPassword to "password here"
set varName to "someVariable"
set varValue to "hello"
set commandString to "curl -u " & indigoServerUsername & ":" & indigoServerPassword & " --digest -X PUT -d value=varValue http://" & indigoServerIPandPort & "/variables/" & varName
do shell script commandString

Here's an example of getting a variable value:

set varValueJson to do shell script "curl -u username:password --digest http://127.0.0.1:8176/variables/someVariable.json"

tell application "JSON Helper"
	set varValueRecord to read JSON from varValueJson
	set varValue to value of varValueRecord
end tell

Note, to use this script you need the Mac App called JSON Helper, which is free from the Mac App Store. This free app does a fantastic job of converting JSON formatted data into AppleScript native data types (like lists and records).

This approach has the advantage of running from any Mac anywhere, whether on the same Mac as your server, another Mac on your local network, or a Mac somewhere out on the internet (use your reflector URL if you're doing the latter).

You can also have AppleScript directly communicate with Indigo's python scripting engine as shown here. That is a slower technique but doesn't use Indigo's Web server and thus doesn't need the username or password embedded in the script.
